This week ISC, one of the largest conferences in the supercomputing calendar, should have been running in Frankfurt. It’s a funny feeling because, as I type, I realise that if it wasn’t for COVID-19 then, instead of being stuck at home, I would have been busy navigating the Messe Frankfurt, going from one session to another.

Rapid Assistance in Modelling the Pandemic (RAMP) initiative

I am the Project Manager of the Rapid Assistance in Modelling the Pandemic (RAMP) initiative, supporting Prof. Mike Cates and the RAMP Steering Committee. RAMP was convened by the Royal Society in the UK to enhance existing COVID-19 initiatives. The motivation was to enhance the modelling teams who inform Government policy through channels such as SPI-M (Scientific Pandemic Influenza Modelling Group), which reports to SAGE (Scientific Advisory Group for Emergencies).

EPSRC has recently announced the new Tier-1 ARCHER2 HPC service and is also in the process of extending the UK's Tier-2 HPC systems. This will give users access to substantial amounts of new CPU and GPU hardware, so it's a perfect time to learn about how to use parallel HPC systems and how to program GPUs.

A public UK HPC knowledge base

Much of these thoughts came out of discussions at the HPC Champions meeting that took place on 16 September 2019 alongside the UK RSE Conference 2019 in Birmingham, UK along with subsequent discussions at the monthly HPC RSE calls.

Online LAMMPS training for ARCHER

In October I ran an online training course teaching current and potential ARCHER users how to run LAMMPS. LAMMPS is a widely-used open-source molecular dynamics (MD) software developed at the National Sandia Laboratories, and is optimised to run well on HPC facilities. It consistently ranks in the top 10 most used programs on ARCHER. Although the course was run on ARCHER and with ARCHER users in mind, I tried to teach users how to use LAMMPS on any platform.

Edoardo Coronado visited EPCC from 18th May–15th August 2019 under the HPC-Europa3 programme. 

Hi! My name is Edoardo Coronado. I am a Mexican PhD student in Technologies of Information at the "Centro Singular de Investigación en Tecnoloxías Intelixentes" (CiTIUS) at the "Universidad de Santiago de Compostela" in Spain. I work on the optimisation of iterative solvers on accelerator devices. I have spent three months at EPCC at the University of Edinburgh under the HPC-Europa3 transnational access programme with Mr Adrian Jackson acting as my host.

Hi! My name is Concetta Cozza. I am a PhD student in Life Science at University ‘Magna Graecia’ of Catanzaro. This summer I visited the research group of Professor Michele Vendruscolo based at the University of Cambridge for three months with the HPC-Europa3 transnational access programme.

Computational optimisation of materials at St Andrews

EPCC staff supported Dr Rincon Bonilla in his HPC-Europa3 research visit to the University of St Andrews earlier this year. 

My name is Mauricio Rincon Bonilla. I work as a postdoctoral fellow at the Basque Centre for Applied Mathematics in Bilbao, Spain, where I combine advanced sampling methods with physico-chemical insights to investigate ion dynamics in advanced battery materials. With the sponsorship of an HPC-Europa3 grant, I was able to spend seven weeks at the University of St Andrews with my hosts Prof. Tanja van Mourik and Herbert Fruchtl, who have lots of expertise in density functional theory for biological and inorganic materials.

Giuseppe Negro undertook an HPC-Europa3 visit based in Edinburgh from 15/04/19–27/05/19. He gives us a brief overview of his visit and the work he undertook.

Hi everyone! My name is Giuseppe Negro and I am a PhD student at the University of Bari in Italy. I work in computational modelling of soft matter systems with Prof. Giuseppe Gonnella and with my collegue Livio Nicola Carenza, who was also an HPC-Europa3 visitor in Edinburgh, at the Department of Physics in Bari. I visited EPCC under the HPC-Europa3 transnational access programme, and I was hosted by Prof. D. Marenduzzo at the Department of Physics and Astronomy of the University of Edinburgh located at the James Clerk Maxwell Building.

Accelerating cloud physics and atmospheric models using GPUs, KNLs and FPGAs

The blog post below is based on the abstract of a talk at the PASC mini-symposium 'Modelling Cloud Physics: Preparing for Exascale' (Zurich, 13 June 2019).

The Met Office NERC Cloud model (MONC) is an atmospheric model used throughout the weather and climate community to study clouds and turbulent flows. This is often coupled with the CASIM microphysics model, which provides the capability to investigate interactions at the millimetre scale and study the formation and development of moisture. One of the main targets of these models is the problem of fog, which is very hard to model due to the high resolution required – for context the main UK weather forecast resolves to 1km, whereas the fog problem requires 1metre or less.
